Book Description
The Efficient Market Hypothesis (EMH) asserts that, at all times, the price of a security reflects all available information about its fundamental value. The implication of the EMH for investors is that, to the extent that speculative trading is costly, speculation must be a loser's game. Hence, under the EMH, a passive strategy is bound eventually to beat a strategy that uses active management, where active management is characterized as trading that seeks to exploit mispriced assets relative to a risk-adjusted benchmark. The EMH has been refined over the past several decades to reflect the realism of the marketplace, including costly information, transactions costs, financing, agency costs, and other real-world frictions. The most recent expressions of the EMH thus allow a role for arbitrageurs in the market who may profit from their comparative advantages. These advantages may include specialized knowledge, lower trading costs, low management fees or agency costs, and a financing structure that allows the arbitrageur to undertake trades with long verification periods. The actions of these arbitrageurs cause liquid securities markets to be generally fairly efficient with respect to information, despite some notable anomalies.

Bachelor Thesis from the year 2015 in the subject Economics - Finance, grade: 2:1 (68%), Northumbria University, course: Business with Financial Management, language: English, abstract: Virtual and computer games are rapidly increasing with the introduction of the smartphone and the app stores across multiple platforms and devices with an increase in games with virtual economies. This dissertation will analyse the efficient market hypothesis, along with commonly known anomalies and information announcements. It will find out whether there are market inefficiencies in virtual games in the form of anomalies, more specifically the intra-day effect. The intra-day effect anomaly is one of many critiques of the efficient market hypothesis and there have been many studies conducted into the intra-day effect. Most research on the intra-day effect anomaly is concerning real world markets and the results have contradicted one another. This study looks at the price change movements of 118 randomly quota sampled player cards within the market of FIFA Ultimate Team. Statistical analysis in the form of mean, standard deviation, and coefficients of variances tests were carried out to identify if there were any market anomalies and reactions to information announcements. A strong correlation between market inefficiencies, anomalies, and information announcements had been discovered within the research of the virtual market in FIFA Ultimate Team. The study actually found that because of an information announcement overreaction and an intra-day effect, at a specific time during a Wednesday, a player could sell their card for potentially 233% more than what they could have an hour earlier. This research study in turn supports that market anomalies do exist in games but it was also discovered that the market is semi-strong form efficient in its reaction post-information announcement.

Book Description
"The process by which securities are traded is very different from the idealized picture of a frictionless and self-equilibrating market offered by the typical finance textbook. This book offers a more accurate and authoritative take on this process. The book starts from the assumption that not everyone is present at all times simultaneously on the market, and that participants have quite diverse information about the security's fundamentals. As a result, the order flow is a complex mix of information and noise, and a consensus price only emerges gradually over time as the trading process evolves and the participants interpret the actions of other traders. Thus, a security's actual transaction price may deviate from its fundamental value, as it would be assessed by a fully informed set of investors. The book takes these deviations seriously, and explains why and how they emerge in the trading process and are eventually eliminated. The authors draw on a vast body of theoretical insights and empirical findings on security price formation that have come to form a well-defined field within financial economics known as "market microstructure." Focusing on liquidity and price discovery, the book analyzes the tension between the two, pointing out that when price-relevant information reaches the market through trading pressure rather than through a public announcement, liquidity may suffer. It also confronts many striking phenomena in securities markets and uses the analytical tools and empirical methods of market microstructure to understand them. These include issues such as why liquidity changes over time and differs across securities, why large trades move prices up or down, and why these price changes are subsequently reversed, and why we observe temporary deviations from asset fair values"--

Book Description
This is the Black & White version of the book, available at a discount, which does not include the research data and analysis tables. There is also a Full Colour version that includes all the research data and analysis tables. What is a Stock Market? How do stock markets operate? Who invests in a stock market and when is it an appropriate tool for investment? Why do we care if a stock market is efficient or not? Where can we find evidence of market efficiency? With what tools can we test market efficiency?These are some of the questions that this book approaches. The Efficient Market Hypothesis (EMH) is a theory in financial economics, developed by Eugene Fama, which states that asset prices fully reflect all available information. Thus, it is implied that stocks always trade at their fair value, making it impossible for investors to "beat the market" via technical or fundamental analysis, since market prices should only react to new information.There are three variants of the EMH: "weak," "semi-strong," and "strong" form. The weak form of the EMH claims that prices already reflect all past publicly available market information. The semi-strong form claims that prices reflect all publicly available information, thus price changes occur to reflect new publicly available information. The strong form adds to this that prices instantly reflect even hidden private "insider" information.Testing the EMH is no easy task: Quantifying the availability of information and its effect on prices and market efficiency is challenging, making research on the subject difficult, time consuming and open to criticism. However, anecdotal evidence suggests that markets at best reach semi-strong form efficiency, with weak form efficiency being the norm. However, even this is challenged by the critics of EMH, via concepts such as Behavioural Finance.This book aims to familiarise the reader with the concept of EMH, covering the fundamentals and relevant literature. We then discuss market efficiency tests for Weak Form Market Efficiency, examining in more detail the day-of-the-week effect and its significance on stock market efficiency. The day-of-the-week effect is defined as a pattern where a certain day of the week has abnormal returns continuously. It is an anomaly that violates the random walk hypothesis, and thus implies that a market is not Weak Form efficient.We put theory into practice through the Empirical Research section which is divided into two parts, looking at two different approaches to researching the day-of-the-week effect, via the examination of actual research examples on a small European stock exchange. Both of these Thesis tested the hypothesis of random walk to determine the authenticity of weak form market efficiency for a small emerging stock market within the EU (the Cyprus Stock Exchange).

Book Description
The past twenty years have seen an extraordinary growth in the use of quantitative methods in financial markets. Finance professionals now routinely use sophisticated statistical techniques in portfolio management, proprietary trading, risk management, financial consulting, and securities regulation. This graduate-level textbook is intended for PhD students, advanced MBA students, and industry professionals interested in the econometrics of financial modeling. The book covers the entire spectrum of empirical finance, including: the predictability of asset returns, tests of the Random Walk Hypothesis, the microstructure of securities markets, event analysis, the Capital Asset Pricing Model and the Arbitrage Pricing Theory, the term structure of interest rates, dynamic models of economic equilibrium, and nonlinear financial models such as ARCH, neural networks, statistical fractals, and chaos theory. Each chapter develops statistical techniques within the context of a particular financial application. This exciting new text contains a unique and accessible combination of theory and practice, bringing state-of-the-art statistical techniques to the forefront of financial applications. Each chapter also includes a discussion of recent empirical evidence, for example, the rejection of the Random Walk Hypothesis, as well as problems designed to help readers incorporate what they have read into their own applications.

Book Description
A new, evolutionary explanation of markets and investor behavior Half of all Americans have money in the stock market, yet economists can’t agree on whether investors and markets are rational and efficient, as modern financial theory assumes, or irrational and inefficient, as behavioral economists believe. The debate is one of the biggest in economics, and the value or futility of investment management and financial regulation hangs on the answer. In this groundbreaking book, Andrew Lo transforms the debate with a powerful new framework in which rationality and irrationality coexist—the Adaptive Markets Hypothesis. Drawing on psychology, evolutionary biology, neuroscience, artificial intelligence, and other fields, Adaptive Markets shows that the theory of market efficiency is incomplete. When markets are unstable, investors react instinctively, creating inefficiencies for others to exploit. Lo’s new paradigm explains how financial evolution shapes behavior and markets at the speed of thought—a fact revealed by swings between stability and crisis, profit and loss, and innovation and regulation. An ambitious new answer to fundamental questions about economics and investing, Adaptive Markets is essential reading for anyone who wants to understand how markets really work.
